Assertion : The dimensional formula for product of resistance and conductance is same as for dielectric constant. Reason: Both have dimensions of time constant.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

C. If assertion is true but reason is false

Step-by-step solution

Both the quantities are dimensionless. Resistance conductance =R 1 / R= [ M ^0 ~L ^0 ~T ^0 ]=1 and Dielectric constant K is dimensionless.
